HP EWS driver, laserjet P2015 printer.

I am running vista 64 bit. I managed to install my printer so that it functions, but Vista keeps telling me that HP EWS needs a driver. Vista is unable to locate and install one. I have no idea what HP EWS even is, and tried googling it, but never found drivers for it.

Its really bothering me getting this message up 1000 times daily. I have tried unisntalling the HP EWS "device" several times, but its there again after the next re-boot. What can I do!??
